Description

[Detailed explanation of the invention] [Field of industrial application] This invention can be sealed, the seal part is discarded after opening, and the seal part of the cap is made short of a plastic bottle lid that can be used as a replacement cap, so that the material can be removed. We devised a means to easily open even this short and small seal while saving money.

[Conventional technology]

The conventional plastic bottle lids shown in FIGS. 1, 2, and 3 have a knob 13 on the seal 2 side that can be picked up with your fingertips when opening the lid. Since the seal is sufficiently large, it can be formed by providing a notch 14 and a further notch 15 on the lower edge of the seal 2 to form the knob 13, or by making a U-shaped window hole 16 on the side. Since the 2nd part of the seal is larger than the knob 13, a cut line 17 leading to the separation line 4 that bisects the cap 1 and the seal 2 can be carved on the seal 2, and the 8 parts at the beginning of the cut of the knob 13 are separated. The separation line 4 is not directly reached, and the cut line 17 allows separation between the 8th part of the knob piece 13 that starts cutting and the separation line 4, so that when sealing the cap, the breakage progresses from the 8th part that starts cutting naturally. I was able to avoid it.

[Problem that the invention attempts to solve]

However, if a plastic bottle lid with a conventional structure with a short seal 2 is used, the bottle neck groove 1
Since the lower root line 5 of the lower corner of the annular protrusion 3 that engages with the cap 1 is the separation line 4 that bisects the cap 1 and the seal 2, a tab 13 is formed on the short seal 2 and the cut is made when opening the seal. The first part 8 cannot be engraved on the second part of the seal apart from the separation line 4.

In addition, with conventional bottle lids, if the separation line 4 is cut open and the cap 1 is used as a replacement bottle, the annular convex portion 3 with a sealing function will adhere to the cap 1, making it difficult to attach the cap. In order to reduce the protrusion of the annular convex portion 3 and weaken the engagement with the constricted groove 11, the seal 2 portion is made longer so that the bottle lid does not tilt and lift off the bottle mouth circumferential wall and lose its sealing function. The 2nd part of the seal is longer, and in the conventional technology, the 2nd part of the seal is longer.
There were some issues that made it impossible to make the section shorter.

[Means for solving problems]

In this invention, a separation line 4 for dividing the cap 1 and the seal 2 into two is carved above the middle of the annular protrusion 3, and from a suitable position of the separation line 4, the seal is passed across the annular protrusion 3 and below this lower corner. A cutting path 6 is carved up to the intersection 10 of the root line 5, and an incision hole 7 is formed away from this from the lower root line 5 to the lower edge of the seal 2, and the upper end where this touches the lower root line 5 begins to be cut. 8, and the lower root line 5 in the circumferential direction between this and the intersection 10 is configured to be separable.

[Effect]

When the tip of the toe is inserted into the incision hole 7 made on the side of the seal 2 and pushed outward along the circumference, the lower root line 5 is gradually torn from the cut start 8 until it reaches the intersection 10, and this seal 2 The part has a shape that can be pinched with your fingertips, so if you transfer it to your fingertips and pull it outward even more forcefully, it will cut up the next cutting path 6 and reach the separation line 4, and then go around the separation line one more time. 4, most of the annular protrusion 3 formed on the seal 2 is separated from the cap 1.
It remains in the bottle mouth 12 as a replacement stopper and can be easily opened.

[Effect of idea]

A separation line 4 that bisects the cap 1 and the seal 2 is carved above the middle of the annular protrusion 3, and a portion of the lower base line 5 of the lower corner of the annular protrusion 3 can be cut off, making it possible to separate the cap from the conventional bottle. Lid cut line 1
7, the separation line 4 and the lower root line 5 can be arranged in two stages at the annular protrusion 3, and the incision hole 7 can be formed along the entire length of the seal 2 up to the lower root line 5. This made it possible to create a seal 2 that was short enough to allow the tip of the toe to be inserted.

In addition, by separating the cutting path 6 that cuts up to the separation line 4 from the intersection 10 on the same circumferential line as the cutting start 8 where the tip of the incision hole 7 reaches the lower root line 5, it is possible to make an incision from the lower edge of the seal 2. Even if the hole 7 is formed up to the annular convex part, as long as no unsealing force is applied, it is possible to seal from the cutting start 8 to the cutting path 6 separation line 4 when sealing the cap or without the break progressing naturally. It became.

Furthermore, when the cap is opened, most of the annular protrusion 3 is removed together with the seal 2, and the cap 1 can be used as a replacement cap that can be easily capped.
The seal 2 can be formed at the time of the bottle lid so that it can tightly fit into the constriction groove 11 of the bottle opening 12.
A plastic bottle lid was obtained which does not lift up the bottle opening 12 even if a force to remove the bottle is intentionally applied after sealing the bottle, even if the part is short.
